Binder used for 3D printing materials

Abstract

The invention discloses a binder used for 3D printing materials. The binder is composed of a component A and a component B at a mass ratio of 2-3:1; the component A comprises, by mass, 50 to 60 partsof acrylic emulsion, 30 to 40 parts of polyvinyl alcohol, 10 to 13 parts of polyvinyl acetate emulsion, 8 to 15 parts of non-ionic polyacrylamide, 20 to 40 parts of soybean protein glue, 2 to 3 partsof sodium hypochlorite, 7 to 12 parts of sodium dodecyl benzene sulfonate, 15 to 20 parts of inorganic gel, 5 to 8 parts of hydroxypropyl methyl cellulose ether, 3 to 6 parts of a stabilizing agent, and 3 to 5 parts of a thickening agent; and the component B comprises, by mass, 35 to 45 parts of polylactic acid, 15 to 20 parts of aerosil, 30 to 40 parts of wax maize starch, 10 to 15 parts of ethylene glycol diacetate, 20 to 35 parts of alumina sol, 8 to 13 parts of allyl methacrylate, 15 to 22 parts of absolute ethyl alcohol, 5 to 8 parts of anhydrous potassium carbonate, 15 to 25 parts of anhydrous magnesium sulfate, 2 to 4 parts of glycol, 5 to 9 parts of nanometer manganous oxide, 3 to 5 parts of a composite initiator, 3 to 6 parts of a curing agent, and 6 to 11 parts of an activator.

Description

technical field [0001] The invention relates to a binder for 3D printing materials. Background technique [0002] With the continuous development of 3D technology, the development and use of many 3D printing materials also promotes the development and production of more auxiliary materials, such as: binder, as one of the most important auxiliary materials in 3D printing technology , and as more and more new materials are used for 3D printing, the performance and characteristics of new materials make most of the current binders unable to be used for 3D printing of new materials. Therefore, a healthy, environmentally friendly, bonding Adhesive with high strength and fast curing speed, which meets the requirements of use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a binder for 3D printing materials in view of the above shortcomings of the prior art. [0004] The technical solution of the present invention to ...
